Hmm, not sure I can tell exactly what you are talking about. I'm familiar with the two nuts behind the trim piece just behind the door. This is where pictures along with instruction would be very helpful.
I guess I'll practice this on my parts car first and see how it goes. If I feel real comfortable with it, I'll do it myself. If not, I'll have a "professional" do it. But, to be honest, I have been less satisfied with so-called "professional" work recently and prefer to do everything possible myself.
